v To all whom it may concern:

' plication is adapted to be used in connection with the bottle washing machines disclosed in thecopending applications of Rockwell L. Gallup, Serial No. (347,005, filed August 31, 1911, and Serial No. (378,316, filed February 17, 1912, but is not limited to such use, as it may be used to obtain equally good results with other mechanism for soaking the bottles.

. In the applications referred to are disclosed means for soaking the bottles in a caustic solution to loosen the labels thereon and for cleaning the bottles. No means is provided, however, for brushing the interior and exterior of the bottles as is sometimes desirable to improve the results obtained. Furthermore, in the devices previously disclosed the bottles must be removed from the conveyor by hand and this generally necessitates the employment of at least two men who remove the bottles and carry them to the bottling machine Where they a re filled.

It is the object of our present invention to provide a means for thoroughly cleaning and brushing the interior and exterior of the bottles, removing whatever dirt may remain 'on the bottles after the soaking operation and leaving the bottles as clean as when new. 'A further object of our invention is the provision of means for automatically removing the bottles from the machine and conveying them to some desirable point, preferably the bottling machine which may be so arranged as to receive the bottles as fast as they are washed and fill them at once.

Other objects and advantages of our in- BOT'ILE-WASHING MACHINE.

Referring to Figs. 1 to 3 of the drawings 1 indicates a frame forming a support for the various parts of the device. A bottle conveyor 2 is mounted on the frame and runs on tracks 3 attached thereto. This conveyor is an extension of the conveyor which carries the bottles through the soaking device as shown in the copending applications, Se-

fcrred to. It is to be'umlerstood, however,

that the present st-ri'icture may be built as a unit which may be fed by hand or otherwise from some other fori'n of washer. The conveyer is intermittently actuated in the dirccs rial No. (347,005 and No. 678,316, above resleeve similar'to' sleeve 15.

being subjected to the soaking operation pass into the present apparatus for further treatment.

A shaft 8 is mounted in suitable bearings onthe, frame land adapted to be driven through the gear 9 andtheworm 11 from the shaft 12 which is in turn driven from any suitable source of power. The oppositely disposed cam wheels 10 are keyed to the shaft 8 and-are'rotated thereby. The

shaft 12 is provided with a bevelpinion 13 meshing with a bevel gear 1 1 secured to the sleeve 15 which is supported in a bearing 16 and adapted for rotation therein. 1 v

A gear 17 is mounted beneath the bevel em -[14 onthesleeve 15 and drives a plurality ofs nnlar gears 17217", 17;and 17 on either side thereof each mounted on a dle 18 is slidably mounted in each of the sleeves 16 and carries atone end a brush member 19. The spindles 18 extend upwardly to loosely engage rod 20 which extends transverselyacross the top of the ma chine and supported at either end by means oflinks 21.611 levers 22 pivoted on the frameat 23.. head 18 is provided at the upper end of thespindles lSto limit the downward movement thereof. a

The levers 22 are provided with cam rollers 23 which run in the cam tracks 2-1 of the cam wheels 10 fast to the shaft 8. The

ends of the levers 22 are connected through the links 25 with a cross head 26 slidably mounted in the opposite sides of the frame 1. The cross head 26 carries a plurality of pairs of slidably mounted rods 27 having at one end clamping members 28 and at the other suitable heads 29 to limi'tthe downward movementsof the. clamping rods. 3 V

In the side of the cam wheels 10 opposite the cam tracks 24 are cam tracks 29 in whichliar-n rollers 30 mounted on the connecting. rods 31 which are provided at one 412 to .turn the screws 43, whereby the meal here 8 are moved to and from thefpivots 38. By this means we are enabled to ad ust toa fnicety the throwof the levers 37 due to'the f movement of the connecting rods 81.

V V The levers 3.7. are connected by means of the links as wlth a member 45 wh ch is slid ably mountedto reciprocate vertically on standards eG-Whichpass through the flanges 48 of the framel, and are rigidly held at the floor. The member 45' is provided with a pressure box 57, which is intermittently con- A squared spini is lowered.

nected through the flexible pipe 58 with a source of water under pressure From the pressure box 57 a plurality of pairs of hollow spindles 59 project upwardly, the spindles being provided with suitable. bearings .60 within the pressure box; '-Th e.spind1es 59 are preferably square 'incros'ssection and pass at their upper'ends through a plurality of sleeves 61 rotatably mounted in bearings in the casing (32 connected to the frame 1 beneath the conveyer 2. The sleeves are provided with intermeshing gears63 which are adapted to be driven by a gearbet mounted A in the casing 62 and connected bymeans of the beve gears 65 and 66 to any suitable source of power, such as the motor 66, whereby the spindles 59 are constantly rotated in their bearings; v e 7 The spindles 59 terminate in tapered nipples 67 which are adapted, when the spindles are raised, to enter the sockets 68 in members 69 andforintherewith a driving con-. I The members 69 are mountedin sultable bearings 1n the member 70 which nection.

extends transversely of the machine and is shda-bly mounted on standards 46 by means of guidesfl. Attached to themembers 69 are a plurality of hollow spindles 73 which extend into the ferrules 7st and are provided at their upper ends with brushes 75. The ferrules 74: are mounted in the sockets 7 1 su'pportedon the frame 1 and are normally pressed upward by the springs 75 disposed between the ferrules and their sockets.

The ferrules are connected at their lower ex-' tremities by means of lugs 72" to the saddle 72 extending transversely of the frame and.

fixed to the rods 71 which loosely engage the member 70 forming a -sliding connection therewith. The rods 71 hold the ferrules 74s in thelr lowermost positions against the action of the springs 75 when the member 7O Mounted .on the member 45 and slidably engaglng the member 70are rods 51 carrying the springs 50 which are adapted to engage and lift the member 70 after the men'r- 7 her 45 has completed a portion of its upward travel and as the nipples 67f engage the sockets 68 to form a driving connection therewith. The springs' 50 preventshocks as the member 70 is lifted.

Supported on the frame '1 adjacentthe v guides'74 isthepressure box '76 adaptedto be intermittently supplied from'a source of water under pressure through the. pipe 77 and providedwvith a plurality of pairs of openings 78 spaced apart a distance equal to the distance between adjacent bottle holders on the conveyer 2, constituting the means for finally rinsing the insides ofthe bottles.

The springs 53 are mounted "on the fram'e lito engage the y member 70 and'pre'vent shock as the mem: ber 70'descends'.

Suitable troughs 79 are provided at either side of the brushing and rising means-to carry off the Water which drains from the bottles during these operations.

The operation of this portion of the machine will, it is thought, be readily understood from the foregoing description. The conveyer 2 is intermittently moved forward a distance equal to that between the successive bottle holders. The shaft 12 revolves continuously and through the medium of the gear train rotates the spindles 18 carrying brush members 19 which are intended to clean the bottoms of the bottles. As the shaft 12 rotates the shaft 8 and the cams 10, the rollers 23 pass into the flattened portion of the cam track 2st and allow the rod 20 and the cross head 26 to descend, lowering the brush members 19 and clamping members 28, respectively, into engagement with the bottles. It is to be noted that both the brushes and the clamping members are provided with lost motion connections with the rod 20 and the cross head 26, respectively, in order that bottles of different lengths may be accommodated and breakage prevented.

Simultaneously with the lowering of the brush members 19 and the clamping memhere 28, the member 45 is raised through the medium of the cam wheel 10, connecting rod 31 and lever 37, thus raising the pressure box 57 and its spindles 59 which are constantly revolved by the gears 61. The nipples 67 engage the sockets 68 and the springs 50 raise the member 70 carrying the spindles 7 3 with their brushes 75. The spindles 73 and brushes 75 are revolved at a high rate of speed through the driving connections with spindles 59. As the member 70 is raised the springs 7 5 which are normally held under tension by the rods 71. are allowed to force the ferrules 7 1 upward simultaneously with the movement of the brushes 75 until the ferrules engage the necks of the bottles. The brushes are thereby inclosed at all times within the ferrules until they enter the bottles preventing undue wear of the brushes as they are reciprocated to and from the bottles. The brushes 75 enter the bottles which are positioned over them by the movement of conveyer 2 and held from rotary movement by the clamping members 28. Water under pressure is simultaneously allowed to enter the pressure boxes 57 and 76, that in box 57 escaping into the bottles throu h the spindles 59 and 73 and the brushes 75 and that in box 76 squirting upward through the openings 78 into the mouths of the bottles. The water which drains from the bottlsYescapes to the troughs 7 9 which carry it from the machine.

causes the brush members 19, the clamping members 28 and the spindles 73 to be withdrawn from the bottles and the conveyor is free to move one step forward before the next operation. It will be seen that in the operation described each bottle is brushed once on the bottom, twice internally and is rinsed twice. The bottles are then allowed to'drain into the trough 79 before leaving this portion of the machine.

The conveyer then carries the bottles to the portion of our device adapted to brush the outside of the bottles to remove any adherin dirt therefrom. v

Refbrring to Figs. 4 to 7 extensions 5 of the reciprocating rods 5, which have been prex iously described as actuating the conveyer 2 through dogs 4, are connected through levers 80 pivoted on opposite sides of the frame and connecting rods 81 to levers S2 pivoted on extensions of the shaft 83 mounted in the frame. The levers 82 carry pawls 84 which are held by springs 85 in engagement with ratchets 86 keyed to the shaft 83. Gears 87 are fixed to the shaft 83 and mesh with pinions 88 keyed to the shaft 89 upon which are mounted a plurality of sprockets 90 for rotation therewith. An endless chain conveyer 91 adapted to be driven in the direction of the arrow in Fig. 4; by the sprockets 90 and carrying a plurality of cup-shaped members 92 is disposed about this portion of the machine, a plurality of tracks 93 being provided upon which turn the anti-friction rollers 94' with which the conveyer is provided. The function of the cup-shaped members 92 will presently appear.

A shaft 94: is mounted in the frame and driven through suitable connections from the motor 66 (see Fig. 2). The shaft 9 is adapted to drive the shaft 97 mounted in the frame 1 and extending transversely thereof through the bevel gear 95 and bevel pinion 96 which is fast to the shaft 97. Mounted on the shaft 97 is a gear 98 which meshes with and drives the gear 99 fixed to the shaft 100. A sprocket 101 is fixed to the shaft 100. A shaft 102 is similarly mounted in the frame 1 and is provided with a sprocket 103 loosely mounted thereon and adapted to be intermittently connected to the shaft through the medium of a clutch 103 as will presently be described. A chain 104.- connects the sprockets 101 and 103 to drive the latter from the former. A plurality of sprockets 104; are fixed to the shaft 102 and serve to drive the chain conveyer or moving support 105, which is provided with blocks 106 of wood or other suitable material, in the direction indicated by the arrow in Fig. 5 along the tracks 107.

Fixed to the rock shaft 129, which is mounted in opposite sides of the frame in .driven sprocket 103,

friction bearings, 'are the cam arms 130 which are disposed in the path of the cam plates 131mounted on the cup-shaped members 92 of the conveyer 91. An arm 132, also fixed to the rock shaft 129, is connected by means of the link 133 to a latch member 134 pivoted at 135 on the frame 1. The latch member 134 is provided with a camshaped nose 136 which normally engages a spring pin 137 .onzthe clutch member 103 and forces the pin outwardly to withdraw it from one of the slots 138 in the sprocket 103, thereby freeing the sprocket 103 from the shaft 102. hen the pin 137 is released it is forced into one of the notches 138 and the shaft 102 is driven from the constantly Arms 129are fixed to the rock shaft 129 and are connected by rods 130 to arms 131 on the connecting rods 81. This connection serves to turn the rock shaft 129 in a direction opposite the movement imparted by the cam plate 131, when the connecting rod 81 moves rearwardly. The rock shaft 129 also carries a plurality of arms 139 each provided with a spring controlled roller 140 disposed in the path of the bottlesmoving on the conveyer 105 and adapted to hold the bottles in proper alinement between the partition 141 (see Fig. 6).

A sprocket 108, mounted on the shaft 100, is connected by means of a chain 109 with asprocket 110 on the shaft 111 mounted in the swinging arms 112 pivoted on the shaft 7 100 on opposite sides of the machine. Fixed to the shaft 111 are the revolving brushes 112 and a second series of revolving brushes 113 are similarly mounted on the swinging arms 112 and are driven from the shaft 111 by means of a chain 114 connecting the sprockets 115 and 116. v

The swinging arms 112 and the revolving brushes 112 and 113 are intermittently moved toward and from the path of the bottles on the conveyers 91 by means of cam plates 147 pivoted on opposite sides of the frame 1 at 148 and having a rolling connection with the swinging arms 112 at 149. The cam plates 147 are provided with cam tracks 150-which are engaged by rollers 151 on the connecting rods 81 so that as the connecting rod approaches its rearmost position preparatory to a new forward stroke thefswinging arms 112 and the brushes are lifted from the pathv of the bot-v -tles. A perforated pipe 152 is mounted on the frame 1 above the brushes 112 and 113 and is suppliedwith water through a pipe 153.. The pipe152 is adapted to spray watervon the bottles as they are brushed.

On the shaft" 97 'are a plurality of bevel pinions-96 and each ,engages and drives a bevel gear 117 [on a shaft 118 mounted in suitable brackets onlthe frame 1. Each, of

the shafts 118 carries a roller 119 of woodi'65 or other suitable material the function of which will hereafter appear.

The end of the previously. described conveyer .2 passes over sprocket-s 120 mounted.

on the shaft. 121 at either end of the machine. Mounted on the shaft 121 are a plurality of plunger wheels 122 each disposed beneath one of the rows of bottle holders on the conveyer 2. Eachplunger wheel 122 is provided with a plurality of plungers .123 of rubber or other suitable material adapted to engage the'neck of a bottle and force it out of its holder. This device pre-.

vents the bottles from sticking in the holdrality of swinging bars 127 which'are nor-.

mally pressedforward by the springs 128. These bars engage the bottoms of the bottles on the conveyer 2 and prevent them from falling onto the conveyer 105 until the preceding bottles have been removed.

Mounted on a rock shaft 142 extending transversely of the frame are a plurality of levers 143 each having at one end a roller 144 adapted toride over a cam plate 131 on the cup-shaped members 92 andat the other end a slidably mounted gate member 145 pivotally mounted. thereon and normally'held up. by a spring 146 but depressible by the lever 143 when the roller 144 engages the cam plate 131.

Adjacent the discharge end a rock shaft 147" is mounted transversely of the machine and isprovided with a lever 148. Atension spring 149 connects the end of the lever 148 with a bracket 150 on the frame 1. Mounted on the rock shaft 147 area plurality of guides 151 normally held in the path ofthe bottles on the conveyer 91 and adapted to guide the bottles onto thevautomatic means for removing them fromthe machine, which will presently be described. Cam levers 152 are fixed to therock shaft '147 "in the path of the cam plates 131 on members 92 ofthe conveyer 91 and are adapted to be lifted by the cam plates to rotate the rock shaft 148 and thereby move the guides 151; out of the path of the members 92 after the bottles have been delivered. 1

The operation-of the. device will be described with respect to' a single bottlealthough it isto be understood that the machine is adapted to handle a plurality of rows of bottles, The 'bottle on the conveyer 2 s. ca ri d fr m h bo b in P rtion of the machine, as previously described, and as the conveyer 2 passes over the sprockets 120 the bottle is forced outwardly by a plunger 123 to loosen it from its holder. The bar 127 prevents the bottle from falling. Upon further movement of the conveyor 2 the bottle slides onto the conveyer 105 between the partition plates 125 and the artitions 141 and into the path of a cup-s aped member 92 on conveyer 91, intermittently actuated through its connection with the reciprocating rod 5. The cam plate 131 on the preceding cup-shaped member 92 in passing the cam arm 130 turns the rock shaft and raises the latch 134 through the medium of the link 133, thus allowing the spring pin 137 on the clutch 103' to enter one of the slots 138 in the sprocket 103. The sprocket 103 being constantly driven through 1ts con- (nections with. the mlotor 66 rotates the sprockets 104 fixed to the shaft 102, thus driving the conveyor 105 until the latch 134 is forced into the path of the pin 137, by the rotation of shaft 129 through rod 130' upon the rearward'movement of the connectmg rod 81. As soon as the pin 137 engages the cam-shaped nose 136 of the latch 134 the pin is forced out of engagement with its slot 138 and the conveyer 105 is no longer driven by the sprockets 103. The bottle is carried by the conveyer 105 to a position beneath the roller 140 where it is stopped by the gate 145 actuated through the lever- 143 by the engagement of the cam plate 131 with the roller 144. As the cam plate 131 passes the roller the gate 145 is raised by the spring 146 but since the conveyer 105 is no longer in motion the bottle is held stationary by the roller 140 until it isvpicked up by a cup-shaped member 92 on the conveyer 97.

The bottle is carried by. the conveyer 91 up the inclined portion of the frame and over the rollers 119 (see Fig. .7) which are constantly rotated through their connection with the motor 66. Simultaneously the forward movement of the connecting rod 81 allows the swinging arm and the revolving brushes 112 and 113 to move into engagement with the bottle. Thebottle is rotated about its longitudinal axis by the rollers 119 and is sprayed with water from the pipe 152 while it is thoroughly brushed by the brushes 112' and 113, thus removing all dirt which may not have been removed in the previous operation. The bottle is then carried by the conveyer 91 over the discharge end of the machine through the guides 151'- which are then lifted by the cam plates 131 to allow the members 92 to pass. The bottle is deposited on the automatic means for removing it from the machine which will now be described.

Mounted at one end-of the frame 1 is a pair of brackets 154 supporting the automatic means for removing bottles from the machine. A base plate 155 extends between the brackets. A. side plate 156 having a beveled nose 157 and a slotted plate 158 having a lining 159 of fiber or other suitable material are similarly mounted forming a. trough. An endless belt 160 extends along the base 155 over the wheels 161 and 162 at either end and beneath the brackets 154. The belt 160 is adapted to be driven from any suitable source of power through the bevel gears 163 and the pulley 164.

Mounted in the brackets 154 is a rock shaft 165 having a plurality of arms 166 fixed thereto each carrying a blade 167 adapted to engage the slots in the plate 158.

A lever 168 is fixed to one end of the rock shaft 165 and adapted to be actuated by means of a connecting rod 169 which operatively engages an arm 170 of the connecting rod 81 and is provided with a collar 169'. At its opposite end the rock shaft 165 is provided with a lever 171 connected at one end to the frame 1 by means of a tension spring 172 which normally draws the lever 171 toward the frame 1 and holds the blades 167 in the position indicated in Fig. 5. WVhcn, however, the connecting rod 169 is moved forward during the movement of the conveyer 91, the collar 169 will be engaged by the arm 170 as the arm nears the limit of its movement and the connecting rod will actuate the lever 168 to turn the rock shaft 165 and move the blades 167 through the slotted plate 158 to form compartments above the belt 160 to receive the bottles. The blades 167 are provided at their lower edges with a portion 173 extending in a direction opposite to the direction of movement of the belt 160. This portion engages the bottles near their bottoms as the belt moves them against the blades and prevents overturning of the bottles.

The operation of the automatic means for removing bottles from the machine will, it is believed, be apparent without further description. The bottles which have been subjected to the outside brushing operation are'carried by the conveyor 91 to thedelivery point. During the forward movement of the connecting rod 81 to actuate the conveyor 91 the connecting rod 169 is, through the collar 169', moved forward to force the blades 167 over the belt 160. The bottles are delivered into the compartments formed by the blades and fall in an upright position onto the belt 160 which is constantly moving. As the connecting rod 81 recedes the blades 167 are withdrawn and the belt 160 carries the bottles still in an upright position to a point outside the machine and delivers them preferably upon a suitable conveyer which carries them directly into the filling machine (not shown).

-The belt 160 is timed to move all of the filling machine may be timed to run slightly fasterrthan the washing machine so the bottles are filled as fast as washed and without being handled by workmen.

\Vhile we have described a constantly moving belt as a means for removing the bottles and this is the preferred embodiment of our invention it is obvious that an intermittently movingbelt may be substituted therefor. 7

It will be readily understood from the foregoing description and explanation that we have perfected a device which, especially when used in connection with the soaking machine disclosed in'the copen'ding applications previously referred to, results in numerous advantages. The bottles are not only cleaned on the inside but the bottoms, which are frequently very dirty, are thoroughly cleaned and all dirt is brushed and removed "from the outside of the bottles. By the use of our device the bottles are delivered as cleanas if they had never been previously used, insuring'against any spoiling of the bottled beer which is a frequent result of uncleanedv bottles.

It is to be understood that the device described and claimed in the present application is adapted to be applied to various forms of bottle washing machines adapted to soak or otherwise treat the bottles and it is to be further understood that various changes may be made in the form, proportions and-arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form herein described being merely a preferred embodiment thereof. 7
